Spain will see widespread heat and stable weather again this Sunday, with clear or lightly clouded skies across most regions. The Agencia Estatal de Meteorología (AEMET) forecasts high maximum temperatures across much of the country, though a noticeable drop is expected along the Atlantic coast, especially in Cádiz and western Galicia. By contrast, temperatures are set to rise along the Mediterranean coast, in the Ebro valley and in the Canary Islands. Some areas may exceed 35°C, with local peaks potentially reaching 40°C in Gran Canaria, Alborán, the Ebro and the southeastern peninsula.
There will be little relief overnight, particularly in the southeast and Balearic Islands, where tropical nights are forecast to continue. These are nights when temperatures do not fall below 20°C. In parts of the Mediterranean and the Canary Islands, meteorologists describe nighttime conditions as exceptionally hot. Early morning hours could bring low cloud and fog to the Mediterranean coast, the Strait of Gibraltar, the Ebro valley and the far northwest. These patches are expected to clear as the day progresses.
Most of Spain will have stable conditions, though the weather will vary by region. High clouds are expected to move in from the west, while afternoon cloud development in the northeastern quadrant could bring showers and thunderstorms. The eastern Pyrenees and lower Ebro area face a risk of locally intense storms. Hail is possible during the heaviest activity. AEMET’s Meteoalerta system provides official information on potentially hazardous weather for up to 72 hours and updates its warnings as conditions develop. Provincial warning levels and affected areas may so change.
These conditions follow a broader pattern of fluctuating summer temperatures across Spain. As an analysis of August weather shifts recently noted, brief cool spells are often quickly followed by renewed heat, while rainfall remains scarce in many regions. This instability challenges residents and authorities adapting to rapid weather changes, especially during peak summer months.
Spain’s climate has impressive regional contrasts. The Atlantic coast typically has milder summers because of oceanic influence, while the Mediterranean and southern inland areas are prone to prolonged heatwaves. Despite their subtropical location, the Canary Islands can experience extreme temperatures in certain microclimates. AEMET publishes daily maximum and minimum temperature observations for individual stations, with recent summaries covering Barcelona and A Coruña, as well as Valencia. Tenerife Sur and Seville are also included. The records let readers compare observed temperatures across Atlantic, Mediterranean, inland and island settings with the day’s forecast. Persistent high temperatures and tropical nights can strain energy resources and affect agriculture, while raising health risks for vulnerable populations in particular. AEMET updates its official warnings as adverse weather develops, helping residents track changing heat and storm conditions.
